Description

Technical Field

[0001] The invention belongs to the technical field of winches, and in particular relates to a webbing winch with an automatic webbing cleaning function. Background Art

[0002] The functions of a winch are similar to those of a hoist. It is often used for traction and handling work and self-rescue and rescue in harsh environments. The workplaces are often mountains, forests, high altitudes, ship docks, deserts, beaches, snowfields, etc. For example, the Chinese invention patent with authorization announcement number CN 105329792 B discloses a winch, including a motor, a transmission shaft, a drum wheel and a gear box. The main working part consists of a drum wheel and a flexible member (nylon rope, wire rope, chain, etc.) wound on the drum wheel. As for the flexible member, the material of the nylon rope is light but the tensile strength is relatively weak, while the wire rope and chain are heavy and inconvenient to maintain. For this reason, our company's technicians have designed a webbing with a certain width, which is both light and has good tensile strength. After market feedback, the operators found that the webbing still has an obvious defect in use, that is, during the traction process, the bottom of the webbing is often close to the ground. In some environments such as mountains and forests, the wide webbing is easily adhered to the surface by twigs and other debris, and the operators need to stop and clean it on the way, which causes a lot of inconvenience. Summary of the invention

[0003] In view of the above problems, the present invention provides a webbing winch with an automatic webbing cleaning function, which can clean the lower part of the webbing at the same time during operation.

The gap is reserved for inserting and fixing the end of the webbing to enhance the strength of the connection.

[0006] Preferably, the center position of the first ring baffle is set as a gear matching part connected to the output end of the reduction gear box after deceleration, and the output shaft of the motor enters the reduction gear box through the gear matching part by setting a connecting shaft, and two concave surfaces of different depths are provided on one side of the first ring baffle facing the second ring baffle, wherein the concave surface close to the inner ring is the worm mounting part, and the concave surface close to the outer ring is the gear turntable mounting part;

[0007] The power output mechanism includes: a fixed ring tightly fixedly sleeved in the worm mounting part, a gear transmission turntable assembly tightly rotatably sleeved in the gear turntable mounting part, a worm wheel coaxially and fixedly connected to the connecting shaft at the position of the gear matching part adjacent to the connecting shaft, a worm meshing with the worm wheel, the worm is fixed on the fixed ring by setting a worm mounting seat, one end of the worm is used as the output end of the power, and the output end of the power transmits power to the outside by setting a synchronous belt assembly. The rotation mode is converted by the combination of the worm and the worm.

[0008] Preferably, the gear-driven turntable assembly includes a turntable body in the shape of a ring, an inner side gear ring fixedly connected to the inner circle of the turntable body and meshing with a spur gear, and a blocking fixing member evenly spaced in an array on the outer circumference of the turntable body. In this technical solution, the structure of the turntable takes up the least space.

[0009] Preferably, the power output mechanism also includes: an external gear ring tightly and rotatably mounted on the outer edge of the first ring baffle; the inner ring of the external gear ring is axially rotatably mounted on the outer peripheral surface of the first ring baffle, and most of the axially empty position of the inner ring is evenly distributed with the same number of mounting accommodating holes as matching the blocking fixing parts; the power output mechanism also includes: a blocking movable part hinged in the mounting accommodating hole.

[0010] Preferably, the blocking movable part includes an articulated shaft, an axial connecting part with one end fixedly connected to the articulated shaft and the other end being a free end, an abutting part hinged to the free end of the axial connecting part, a lock box which is sleeved on the outer periphery of the axial connecting part and whose inner top wall can simultaneously sleeve the abutting part by means of a tension spring, and unlocking wheels are respectively arranged on both sides of the lock box; a reset torsion spring is sleeved in the middle of the articulated shaft.

[0014] Preferably, the webbing bottom cleaning assembly includes a webbing transition rod arranged in the direction of the webbing entering and exiting and parallel to the reel, a transfer gear meshing with the external gear ring is rotatably provided on the side of the webbing transition rod close to the external gear ring, and a cleaning piece is arranged in parallel on the outer side of the adjacent webbing transition rod; the cleaning piece is fixedly provided with a driven gear meshing with the transfer gear on one side of the transfer gear.

[0015] In summary, the present invention has the following advantages compared with the prior art:

[0016] The present invention utilizes the gap in the drum for installing the webbing to lead out the power of the motor. The original winch is basically unchanged in terms of the overall structure. The friction resistance of the cleaning part is very small when cleaning the webbing, so the power consumption of the winch can be ignored. The core technology of the present invention lies in how to lead out the power of the motor after passing through the relatively slow speed of the drum. A power output mechanism is designed based on this. The power output mechanism mainly consists of multiple groups of blocking fixed parts and blocking movable parts for power transmission. During the transmission process, several blocking movable parts will rotate to avoid after colliding with the connecting block in the drum when surpassing the drum, and the remaining blocking fixed parts and blocking movable parts will continue to transmit power, thereby completing continuous power transmission. In the shutdown state, when the clutch assembly switches to separation, the power output mechanism will not have any effect on the process of pulling out the webbing.

[0017] In summary, the cleaning element of the present invention will continuously rotate outward to clean the bottom of the ribbon after obtaining a fast rotation speed, thus preventing debris from being drawn into the reel to a great extent. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0033] Example 1

[0034] like Figure 1-3 As shown, a webbing winch with automatic webbing cleaning function, the basic structure of the winch in this embodiment is similar to most winches in the prior art, including: a reel 100 located in the middle and a motor 200 and a reduction gear box 300 respectively located at both ends of the reel 100, wherein a clutch assembly is provided in the reduction gear box 300, the clutch assembly is in manual mode and the operating handle 310 is externally arranged, a brake structure 400 of an extrusion tensioning mode is provided inside the reel 100, a power output mechanism 600 for directly outputting the original rotation speed of the motor 200 is also provided on one side of the reel 100 close to the reduction gear box 300, and a webbing bottom cleaning component 700 for receiving power from the power output mechanism 600 in the direction where the reel 100 is located in and out of the webbing 01;

[0035] During operation, the operating handle 310 is switched to the disengaged state of the reduction gear box 300. At this time, the reel 100 can rotate freely and pull out the webbing 01. After the end of the webbing 01 is fixedly connected to the towed object, the operating handle 310 is restored to its initial state. After starting the motor 200, the reel 100 slowly rotates to start the traction action, and the cleaning component 700 quickly rotates to clean the lower part of the webbing 01 to prevent branches and other debris from being drawn in. The brake structure 400 is in the servo protection state, that is, if the motor 200 fails and the reel 100 reverses, the brake structure locks the reel 100, thereby ensuring the stability of the towed object, which is particularly important during high-altitude lifting.

[0036] The basic component of the present embodiment is the reel 100, and each part of the power output mechanism 600 outputs power based on the connection with the reel 100, such as Figure 4-5 As shown, both ends of the reel 100 are provided with two ring baffles. For the convenience of explanation, they are named in order from one end where the reel 100 is connected to the reduction gear box 300 to the other end as the first ring baffle 101, the second ring baffle 102, the third ring baffle 103, and the fourth ring baffle 104. The roots of the second ring baffle 102, the third ring baffle 103, and the fourth ring baffle 104 are welded to the outer surface of the reel 100. At the positions near the outer edges of the first ring baffle 101 and the second ring baffle 102, a plurality of connecting blocks 02 are provided to connect the first ring baffle 101 and the second ring baffle 102 by bolts. Through connection; a connecting part 03 for fixing the webbing 01 is provided at the root of the second ring baffle 102 and the third ring baffle 103, and a certain distance of gap is set between the first ring baffle 101 and the second ring baffle 102, the third ring baffle 103 and the fourth ring baffle 104, respectively, which is convenient for operators to operate when the webbing 01 is fixed to the connecting part 03; the reduction gear box 300 first transmits the power after deceleration to the first ring baffle 101, and the first ring baffle 101 is connected to the entire reel 100 through the connection of the connecting block 02.

[0037] like Figure 6As shown, the center position of the first ring baffle 101 is the gear matching part 101a connected to the output end of the reduction gear box 300 after deceleration. The output shaft of the motor 200 enters the reduction gear box 300 through the matching part 101a by setting a connecting shaft 04. After receiving the power transmitted by the connecting shaft 04, the reduction gear box 300 reduces the speed and increases the torque and transmits it back to the gear matching part 101a. This is the prior art and will not be described in detail. Two concave surfaces of different depths are provided on one side of the first ring baffle 101 facing the second ring baffle 102, wherein the concave surface close to the inner ring is the worm mounting part 101b, and the concave surface close to the outer ring is the gear turntable mounting part 101d;

[0038] The power output mechanism 600 includes: a fixing ring 610 tightly fixedly sleeved in the worm mounting part 101b, a gear transmission turntable assembly 620 tightly rotatably sleeved in the gear turntable mounting part 101d, a worm wheel 630 coaxially and fixedly connected to the connecting shaft 04 at the position of the gear matching part 101a adjacent to the connecting shaft 04, a worm 640 meshing with the worm wheel 630, and the worm 640 is fixed on the fixing ring 610 by setting a worm mounting seat 650. The two ends of the worm 640 can select one end as the output end of the power according to needs, and the output end of the power is transmitted to the outside by setting a synchronous belt assembly 660, that is, the output end of the power is fixedly connected to one of the synchronous wheels of the synchronous belt assembly 660, and the other synchronous wheel is fixedly connected to a spur gear 670; the synchronous belt assembly 660 is extended toward the axis direction of the connecting shaft 04 and the two axes are perpendicularly intersecting, and its purpose is to mesh the spur gear 670 with the gear ring to continue to transmit power to the outside;

[0039] The gear-driven turntable assembly 620 includes a turntable body 621 in the shape of a ring, an inner side gear ring 622 fixedly connected to the inner ring of the turntable body 621 and meshing with the spur gear 670, and a blocking fixing member 623 evenly spaced in an array on the outer peripheral surface of the turntable body 621;

[0040] like Figure 7-9 As shown, the power output mechanism 600 also includes: an external gear ring 680 tightly and rotatably sleeved on the outer edge of the first ring baffle 101; here, the inner ring of the external gear ring 680 is a small part sleeved on the first ring baffle 101, and the empty position of the inner ring is evenly provided with the same number of mounting holes 681 matching the blocking fixing member 623, and the position where the external gear ring 680 and the outer edge of the first ring baffle 101 are sleeved can be further provided with a protrusion and a groove or other types of matching to prevent the two from separating (not shown in the figure); the power output mechanism 600 also includes: a blocking movable member 690 hinged in the mounting accommodating hole 681;

[0041] like Fig.10As shown, the blocking movable member 690 can be received in the accommodating hole 681, and includes an articulated shaft 691, an axial connecting member 692 with one end fixedly connected to the articulated shaft 691 and the other end being a free end, a supporting member 693 hinged to the free end of the axial connecting member 692, a lock box 694 sleeved on the outer periphery of the axial connecting member 692, the inner top wall of which is provided with a tension spring 06 so that it can also sleeve the supporting member 693 at the same time, and unlocking wheels 695 are respectively provided on both sides of the lock box 694; a reset torsion spring 07 is sleeved in the middle of the articulated shaft 691, and under normal conditions, the reset torsion spring 07 presents the overall blocking movable member 690 as follows Fig. 9 The open state shown;

[0042] During operation, the rotation direction of the reel 100 is consistent with the rotation direction of the gear drive turntable assembly 620. Figure 8 , Fig.11 , Fig.12 For reference, they all rotate in the clockwise direction. The speed of the gear drive turntable assembly 620 is the speed of the synchronous motor, so the speed is much greater than the rotation speed of the reel 100. Therefore, the gear drive turntable assembly 620 continuously surpasses the reel 100. One end of the tension spring 06 in the blocking movable member 690 is hung on the top wall of the lock box 694 and the other end is hung in the shaft connection member 692. Under normal circumstances, the lock box 694 is pulled down to lock the shaft connection member 692 and the abutment member 693 into a rigid combination, and the blocking fixed member 623 is as shown in FIG. Fig.12 As shown, the position where the upper part contacts the abutment member 693 is an elastic pin 623a, and the circumferential surfaces of both ends of the elastic pin 623a are supported by a compression spring. Under the action of external force, the elastic pin 623a can overcome the compression spring and move to the side with a smaller center diameter relative to the turntable body 621. The purpose is that when the blocking movable member 690 is opened, the abutment member 693 and the elastic pin 623a collide with each other, so that the elastic pin 623a can overcome the compression spring and move, and the movement is to reduce the center diameter relative to the circle, so that the abutment member 693 can pass over the elastic pin 623a, and the elastic pin 623a is reset under the action of the compression spring, so that the elastic pin 623a can collide with the abutment member 693, thereby pushing the blocking movable member 690 under the rotation of the turntable body 621, and the blocking movable member 690 drives the external gear ring 680 to rotate;

[0043] Due to the difference in rotation speed between the reel 100 and the gear drive turntable assembly 620, as shown in FIG. Figure 6 As shown, a certain gap is provided at the outer edge of the first ring baffle 101 after it is connected to the connecting block 02, and the gap allows the blocking movable member 690 to pass through when the gear drive turntable assembly 620 rotates beyond the reel 100 (see Figure 8), in addition, in order to allow the blocking movable member 690 to pass smoothly, it is also necessary to convert the shaft connection member 692 and the abutment member 693 from a rigid combination into a state in which the abutment member 693 can rotate. For this purpose, the connecting block 02 is designed to have an inclined surface inclined in the direction of rotation on the side facing away from the rotation direction, and two triangular unlocking members 08 corresponding to the two unlocking wheels 695 are provided on the inclined surface, and the bevel of the unlocking member 08 faces upward, and the unlocking wheel 695 will move upward with the bevel when entering, such as Fig.11 As shown, when the blocking movable member 690 drives the external gear ring 680 to rotate and is about to surpass the reel 100, the unlocking wheel 695 first conflicts with the unlocking member 08, and the lock box 694 overcomes the tension of the tension spring 06 and moves upward until the hinged position of the shaft connection member 692 and the abutting member 693 is exposed, and the hinged position immediately conflicts with the inclined surface of the connecting block 02 under rotation, and the abutting member 693 generates a certain rotation under the abutment, thereby causing the abutting member 693 to break away from the elastic pin 623a, and then the lock box 694 conflicts with the inclined surface of the connecting block 02, the unlocking wheel 695 is also separated from the unlocking member 08, and the blocking movable member 690 is restored. The assembly is restored to rigidity, and part of the elastic force of the return torsion spring 07 is overcome under the resistance of the connection block 02 to enter the receiving hole 681, and the other part slides against the outer peripheral surface of the connection block 02 until it completely passes over the connection block 02. After passing over the connection block 02, the return torsion spring 07 makes the blocking movable member 690 reset. During the reset process, the abutting member 693 hits the elastic pin 623a, and the above-mentioned situation occurs. After the abutting member 693 passes over the elastic pin 623a, the blocking movable member 690 drives the external gear ring 680 to rotate, so that each blocking movable member 690 continues this action, so that the external gear ring 680 can rotate continuously;

[0044] like Figure 1 and Fig.13 As shown, the webbing bottom cleaning assembly 700 includes a webbing transition rod 710 arranged parallel to the reel 100 in the direction of the webbing 01 entering and exiting, a transfer gear 720 meshing with the external gear ring 680 is rotatably arranged on the side of the webbing transition rod 710 close to the external gear ring 680, and a cleaning member 730 is arranged parallel to the outer side of the adjacent webbing transition rod 710; the cleaning member 730 is fixedly provided with a driven gear meshing with the transfer gear 720 on one side of the transfer gear 720, and through the rapid rotation of the external gear ring 680, under the above transmission path, when the traction is started, the cleaning member 730 rotates rapidly outward to automatically clean the bottom of the webbing outward to prevent various debris from entering the reel and winding. The cleaning member 730 can be a brush or a fan blade.

[0045] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
